如何将命令行参数包含“|”传递给java程序

Question

One of the arguments passed to my java program is like this, ab|cd . Initially, when I run the java program, like this,

$ java className ab|cd

it fails, since | is interpreted in the linux shell as a pipe symbol. So only ab is passed into java program. So I made a second attempt:

$ java className "ab|cd"

This time, "ab|cd" is passed in, but the value includes the double quotes. What the program is really intended to have is ab|cd . How can I pass in the correct value without the quotes?

Answer 1

在命令shell中，您可以使用'\\'字符转义字符。

 java className ab\|cd

Answer 2

Try (for Linux):

$ java className ab\|cd

For Windows:

java className ab^|cd

Answer 3

您可以像以下代码一样使用转义字符：

$ java className ab\|cd

Answer 4

尝试这个，

"\\" is used inorder to nullify the effect of the characters which have special meanings.

java className ab\|cd

Answer 5

Maybe try this:

arg="ab|cd"
java className $arg
